SECONDARY outcome

Timeframe: At baseline and week 12

Insulin sensitivity is measured with HE clamp. Glucose Infusion Rate was titrated to maintain blood glucose concentration at the fasting glucose level. Plasma samples for glucose was obtained at 10-minute intervals starting 30 minutes before the clamp, to quantitate rates of whole-body glucose disposal. Difference from baseline at 12 weeks is calculated and compared to placebo arm
